Be it-known that I, \VILLIAM An rrwn Cannrcorrr a subject of the King of Great Britain and resident; of Johanneslmrg, Transvaal, have invented certain new and useful Means for Separating Liquids from Crushed-Ore Products, of which the followmg is a specification.

-Th1s invention relates to means for sepa' rat ngliquid; such as water, cyanid or other solvent; solution or wash water, from crushed ore, prodnets.

,The invention 1Sj applicable for use in the tre'a tinentoil either elassof such prod netssands oif-sli1nes"and for either.intern'littent or eontiniun s operation, W'ith the means at present in usefor separating liquid from sue 1 products, holes or passages, form throng-lithe inassof solids in 'tlielse arat ing the liquidfthrough'l the aperture in the bottom of the vessel. 'Now the object of the inrention is. to obviate this and to secure a constant thick underthn'v from the'vessel by preventing the foruiz itio'n of holes or passages through, the fsettleduuass. i

Theinvenlion may be utilized in spitzlgasteiror sindlar conical classifiers, or in tanks, rats. or vreceptaclesof other shape, employed for thetreatment uf'erushed ore produets.

To the attainment of the objeetpt the invention l" eui 'iloy a barrier which may take the form of a serratial or noiehed or perforated diaphragm or a serrated or notched and perforated diaphragm or two or more of such diuphragms which are positioned, inside the vessel below the normal level of the mass of seltlwlmaterial.

The practicalapplication of my invention is illustrated in and will he further described in connection with the llt'fltllllptlll)" ingtwo' sheets of drawings, in 'whirh Figure 1 illustrates in seelioual elevation, the invention ada 'ited to an ordinary ronical-classifier! inverted conical vessel r-n|ninonlyemployed in the treatment. ol" auril"- erous ores for removing the hulk of liquid from-a mixture of liquid and (rushed ore products. Fig. 2 is a plan of Fig. I. Fig. 3 is theadaptat-ion of the invention another common type of tank or rat, and lg. Lisa plan of a tank as shown in Fig.

Referring more pa rticularly to. the; ar- 'angement illustrated in Fi 1 and 2,1 represents an inverted conical i essel into the upper end of which t'l e mixture of crushed ore products and liquic is introduced through the. medium of the "ertical inlet ipe.2 whiehanay, as is usua be arranged t o.d is charge the mixture 01 ltO or above a bafile plate 3 in. order the m )18 effectually to distribute the mixture Wl :hin. the vesseL Thevessel 1. will ordinarily be. provided with. the

l el-J ofi'lthe; settle 1. represents the norma solids.

At .a suitable point normal level 5 I arrang diaphragms 6. As. illu ures it takes the form 0: serrated, or notched dis k, indentationsor serrations Tprovide-ormonstitute the passages through which t-he settled solids pass on thei way to the-outlet 8 at the-bottom of the vessel. Instead, of employing one. serratee diaphragu'i 6 as shown a plurality may lit? employed and if desired instead of or in addition to want ing' the diaphragn'i or (liaphragms cireumterentially it or they may alsobe perforated preferably ate! in pnximity to. the-peripl'iery.

in Fig. 3 I illustrate the application of the invention to thatfor n of" tank 9.which is made e ylimlrical'for the greater portion of its height and of inv erted-eonical form In this case the pulp or mixture of liquid and crushed ore-prodllltlS means of the )r pointsbelopwstlite :trated in. these-.fi' a eireumfemntiialg' inlet pipe 1) and distrilu-iting hallle ll. the settled solds bewithdrawn through the discharge a ierture- 12 in the bottom of the vessel 1) art] the overflowbe rm-eived by the annular rim launder13. In,

as for, withdrawing.

The peripheral may he introduced into, the vessel by a one or mpreof-the ,1

apart, one above the other, and at some depth below the normal level, indicated by the dotted line 16, of the settled solids. In this type the diaphragm or diaphragms may also be circumfereutially notched as shown in dotted lines in Fig. 4.

In Fig. 4 a vessel 17 of the configuration shown in Fig. 3 is illustrated provided with one of the perforated diaphragms 18. For the type of vessel illustrated more particular] y in Figs. 3 and 4 the apertures or perforations 15, 1.) formed in the diaphragm or diaphragms 1- 18, are preferably uniformly distributed over the whole area thereof so that each of said perforations or apertures serves a more or less equal area.

The diaphragms may be made of wood or sheet metal or any other suitable material andthcy; may be supported inside the vessel as shown or ir'rany other com-'enient manner.

. ln operation, the ore pulp is delivered through the verticalintlow pipe over the horizontal battle slightly below the surface of the pulp in the center of the tank which is kept nearly filled to the top with sand.

.The diaphragm, by supporting a considerable depth of settled sand, prevents any change in consistency or breaking away of the thick sluggish underflow while the-large size openings at the bottom of thetank preelude choking. Large containing very little moisture canthus be delivered with a steady flow. What I claim as my invention and desirc to protect by Letters Patent is 1. In a. separator for liquids and crushed ore products, a'vessel for receiving the mixture of solids and liquids, said vessel havin an outlet adapted to discharge the settle precincts, and a barrier in said vessel 'arranged below the level of the settled products and adapted to prevent the formation quantities of pulp name to this specification in the of passages throu h said settled products while permitting t e passage of said products to said outlet. v

2. In a separator for liquids and crushed ore products, a vessel for receiving the mixture of solids and liquids, said vessel having an outlet adapted to discharge the settled products, and a barrier in said vessel arranged beloiv the level of the settled products and adapted to prevent the formation of )assages through said settled products, sai barrier having apertures to permit the passage of said products to said outlet.

3. Ina separator for liquids and crushed ore products, a vessel for receiving the mixture of solids and-liquids, said vessel having an outlet adapted to discharge-the settled products, and a barrier in said vessel arranged b0l()\\' the level of the settled prod ucts and adapted to prevent the formation of passages through said settled products, said barrier having passages between it, and the walls of the tank to permit the passage of said products 'to said outlet.

- 4. Ida separator for liquids and crushed ore products, a vessel for receiving the mixture of solids andlliquids, said vessel having an outlet adapted to discharge the settled products, andia barrier in said vessel arranged belovv the level" of the settled products and adapted; to prevent the formation of a$ages through said settled products,-

sai barrier having passages between it and the walls of the tank and openings through it to permit the passage of said products to said outlet.

In testimony whereof I have signed my presence of two subscribing witnesses.
